Does he like mirrors Nell? I found that Jacob LOVED looking at himself in the mirror for tummy time! I would put down one of those hand-held mirrors that can have their own little stand thing on them, and prop it up next to him....or I would take him to different mirrors around the house......

The other thing Jacob liked doing was looking at photos (he still does). So I quite often show him pictures of family members, pets etc and say their names, tell stories about them etc.

Some really simple things like putting some dry pasta in an empty coke bottle will make a cool noise too (just make sure the lid is super-glued on!).

HTH!
